I am currently a Postdoctoral Researcher at Northeastern University, Boston, MA. I received Bachelor degrees in Computer Science Technology and English from Taiyuan University of Technology, Shanxi, China in July 2004. From 2004 to 2006, I was a PhD student in School of Automation Science and Electrical Engineering, Beihang University (BUAA), Beijing, China, and worked on pattern recognition, robotics and computer vision. In January 2007 I moved to Canada to start research on public health modeling in Software Research Lab in Department of Computer Science, University of Saskatchewan, where I received my Master of Science in Computer Science in December 2008 with the thesis “Application and Evaluation of Local and Global Analysis for Dynamic Models of Infectious Disease Spread”. After that I joined School of Informatics and Computing at Indiana University as a PhD student in January 2009. In September 2011, I transferred to Northeastern University to continue my PhD program with Prof. Vespignani. In May 2014, I received PhD in Computer Science from Northeastern University with the dissertation titled "Contagion and ranking processes in complex networks: the role of geography and interaction strength". My research primarily focus on research projects modeling epidemic spreading dynamics on complex networks and modeling, mining human behaviors on social networks.
